Description

Technical Field

[0001] The present invention relates to the technical field of underground water distributors, and in particular to an underground intelligent water distributor. Background Art

[0002] In the process of oil production, in order to maintain the oil layer pressure and improve the oil layer recovery rate, it is necessary to use a downhole water distributor to inject the ground water into the oil layer. The water distributor is a special downhole tool used to quantitatively inject water into each oil layer.

[0003] However, during the use of traditional downhole water distributors, the water injection port on the downhole water distributor is prone to allow debris in the well to enter the water injection port when not injecting water, causing blockage of the water injection port. Even if a protective net is installed on the outside of the water injection port on some downhole water distributors, the outer surface of the protective net is easily covered by debris during long-term use, thereby affecting the normal water injection work of the downhole water distributor. In addition, since the diameter of the water distributor body is much smaller than the diameter of the casing, and the outside of the water distributor body lacks an effective centering guide structure, the outer wall of the water distributor body is prone to friction and collision with the inner wall of the casing, thereby affecting the service life of the water distributor body. Summary of the invention

[0048] The working principle of this embodiment is as follows: during oil production, when it is necessary to inject ground water into the oil layer, the water distributor body 1 is first lowered into the well, and then, with the cooperation of the support ring 301, the vertical connecting column 302 and the guide roller 303, the axis of the water distributor body 1 and the axis of the casing 7 are always on the same axis, thereby ensuring that the water distributor body 1 is in the center position inside the casing 7, avoiding friction and collision between the outer wall of the water distributor body 1 and the inner wall of the casing 7.

[0049] When the water distributor body 1 reaches the designated position, the ground water is transported to the inside of the water distributor body 1 through the inside of the packer 6, the inside of the water inlet pipe head 401, the inside of the hydraulic box 4 and the inside of the water outlet pipe head 402 by the ground water delivery equipment, and then the ground water is injected into the oil layer through the water injection port 106 on the water distributor body 1.

[0050] When the water injection port 106 stops discharging water, the protective net 105 protects against debris in the well from entering the water injection port 106, thereby preventing the water injection port 106 from being blocked. During water injection, the water immersion sensor 8 senses the water and transmits a water signal to the intelligent controller 104. The intelligent controller 104 then starts the drive motor 205, which drives the drive disc 202 to rotate. The drive disc 202 then drives the lower end of the connecting rod 203 to rotate. The upper end of the connecting rod 203 moves back and forth with the clearing brush 204. The clearing brush 204 that moves back and forth removes debris covering the front side of the protective net 105, thereby preventing the normal water injection operation of the water distributor body 1 from being affected.

[0051] During the water injection process, when the water passes through the hydraulic box 4, the downward flowing water will drive the hydraulic impeller 404 to rotate, and then the hydraulic impeller 404 drives the rotating shaft 403 and the first synchronous pulley 405 to rotate, and then drives the second synchronous pulley 503 and the rotating shaft of the micro generator 501 to rotate through the synchronous belt, and then the micro generator 501 starts to generate electricity, and finally the generated electric energy is stored through the arc-shaped rechargeable battery 109.
